1. A method of jump-starting a hydrogen fuel cell-powered aircraft, said method comprising:
accessing a fuel cell stack containing latent oxygen therein;
accessing a hydrogen fuel source;
providing hydrogen from said hydrogen fuel source into said fuel cell stack;
causing said hydrogen to mix with said latent oxygen in said fuel cell stack and generate a voltage; and
providing said voltage to a motor assembly of said hydrogen fuel cell-powered aircraft to cause said motor assembly to rotate an elongated shaft having a compressor operably coupled to the elongated shaft, wherein the compressor is rotated to introduce additional oxygen into said fuel cell stack.
